The disclosure discloses a method for transmitting compressed rights. The method includes that: a terminal negotiates a compress algorithm with a server; the terminal requests the server through an 'Extensions' field in a rights object request message to transmit the rights in compression format; the server generates a rights object response message according to a standard approach, compresses the rights in the rights object response message according to the negotiated compress algorithm, and generates a compressed rights object response message and sends the compressed rights object response message to the terminal; the terminal receives the compressed rights object response message, decompresses the rights in the received rights object response message according to the negotiated compress algorithm, and generates a decompressed rights object response message. The disclosure also discloses a system for transmitting compressed rights through which the volume of data in the Rights Object Acquisition Protocol (ROAP) communication can be reduced and the reliability of digital rights object transmission and user experience are improved.

A method and system for fast handover in hierarchical mobile IPv6 includes: a mobile node which transmits a proxy route request message to a previous access router of the mobile node according to a handover expectation provided by the link layer, the previous access router transmits a network prefix information of a new access router of the mobile node to the mobile node; the mobile node which generates new care-of address according to the network prefix information; after the mobile node moves to a target network, an optimistic duplicate address detection is performed on the care-of address. The disclosure can simplify the handover procedure of hierarchical mobile IPV6 of the mobile node, reduce the signaling interaction in handover process, and shorten handover delay.
